The article deals with the issues related to the methodology of detecting possible reso-
nant flexural vibrations of a rocket subjected to wind loads. As part of the methodology
under development, we provide an algorithm for calculating the first approximation of
how the rocket body responds to external wind loading. We present the calculation re-
sults as a table containing full wind loading distribution over altitude. Besides, so as to
more thoroughly investigate the issue of resonant flexural vibrations appearing, we ana-
lysed the effect that the perturbing factors of wind loading have on the behaviour of a
cylindrically shaped structure. It showed a significant increase in the lateral force as
compared to drag for a quite narrow Strouhal number range. We present the results in
the form of plotting power characteristics (ratios of the lateral force coefficient to the
drag coefficient) against the Strouhal number.
Keywords: rocket, lateral force, wind load, resonant flexural vibrations
